AUT()MATICI STOPPING MEANS FOR Application filed .April 523, 1919.

enced because of tlietendenGy of the tractor to rear up when an@'obstruction is encountered, as for instancefI when a'plow'strilres aroot or a stump.' Unless the power can be shut oit very quickly,I thetractor is'liable to be overturned.'

An object of my iiivention is to .provide a device by means of which atractor may be automatically stopped.' whenever there is any tendencyfor thrr1 tractor to rear.l

further object, of my invention is to 1 provide a devicev willich may beeasily attaclied to any tractor and which will operate instantly to stop-the tractor when the.` latter has reacheda predetermined angle' withrespect to the ground over which it is'travelz. y ing, therebypreventing Vthe overturning oi:

the tractor. y

, Other objects and advantages will appear in thefollowing/speciicaticn, and the novel features of the/ invention will beparticw attached to any larly pointed ont in the appended claims.

My invention is illustrated in the accom-` panying'diawing forming apart of this specicatiom/and wherein:

Figure l is ay side 'View of a portion of a tractor anda plow drawnthereby, the trac tor being equipped with my improvedstop-4 ping device,and

Referring now to Fig. 'therein a tractor having a body portion, l uponwhich is carried a clutch lever 2. The tractor has the usual tractorwheels such asv that shown at 3; Any implementymay be drawn bythetractor. In the present in stance I have shown a plowt. The means forattaching the plow to the tractor is shown in I? ig. 2. In thisfigure aUshaped .14, I have shown' member which may be made of sheet metal s crof 'cisltnictah is bolted rigidly to the rigid Speccaton of LettersPatent.

The member 7 8 at one end, the secured to the plow., as shown draw-bar 6ofthe tractor.

opposite end being rigidly tongue or draw-bar 9 of the in Fig. Themember 5 is loosely mounted pintle It constitutes inv fact a half hinge.The pintle 8 has an elbow 8il and is provided at its end with anupturned portion Sb having a slot 8c. An arm 11 is pivotally mounted atl2on the laterally extending portion of the pintle 8 and extends throughthe slot 8, the outer end of the arm being connected with the clutchlever' 2 by means of the chain 12.

rointhe; foregoing description of the various parts of the device, theoperation thereof may be readily understood. When the tractor lispulling the plow under ordinary conditions, the arm 1l will move up anddown in the slot 8e ment .of the tractor. load becomes too` great aswhen the plow following the movestrikes a 'stump or root, thus tendingto cause the latter moving upthe tractor 'to rear, wardly and carryingwith it the clutch lever 2, bi-'ings the arm. 1l to the top of theslot.4

The hinge members 'Z- and 5 are heldin subposition since the line offorce exerted by the tractor is substantially parallel with the ground.ther movement of the tractor will clutch lever to be swung downwardly,thereby releasing the clutch and stopping the tractors' A It is obviousthat the arm 11 might be movement would l instance-fthe spark lever orthe throttle lever', Without departing from the spirit of the'invention.

Any furcause the' When, however, the l movable member fwhose result inthe stopping of' The device, which has been tried out in practice, hasbeen found to operate successi instance to stop the tractor when it isstalled by .an excessive load.

ico'

While I have shown the tractor as drawing'l a plow, it is obvious ot'suitable. implement might be 'used without departing from the spiritandscope of the invention.

The length of the chain l2 may be adjusted so 'that the`Y stopping ofthetractor may 'be set for any predetermined angle with vrespect totheground over lwhich the tractor is proceeding.
